Abstract

A wet wipe for reducing body perspiration, comprising an effective amount of an antiperspirant, comprised in a solution or suspension based on a mixture of inert organic materials and water or on one or more inert organic materials, and impregnated on a sheet material carrier. The antiperspirant may be provided in aqueous solution. The wet wipe may further comprise conventional cosmetic additives that contain pH buffering materials, preservatives and perfumes.

Description

ANTIPERSPIRANT WIPES

Field of the Invention

The present invention relates to antiperspirant compositions. More particularly, the invention relates to antiperspirant products in sheet material form, such as towellettes, wipes and napkins.

Background of the Invention

Excessive sweating is a very common problem that plagues both genders

throughout the year, and particularly during summer months. Sweating

is largely responsible, not only for discomfort, but also for bad odors which

are caused, e.g., in the armpit, by bacteria growing on the skin. The

growth of bacteria is accelerated by sweat, and so is the creation of bad

odors which are related to the decomposition products resulting from the

reaction which takes place on the surface of the skin between the bacteria

and certain body secretions. Perspiration adds to the problem of spreading

of body secretion and enhances it.

One way to control body perspiration is hygiene. Cleaning the body often

It is therefore an object of this invention to provide antiperspirant products that overcome all the aforesaid prior art drawbacks.

It is another purpose of this invention is to provide antiperspirant products that are effective in decreasing sweat.

It is yet another object of the invention to provide antiperspirant agents that can be easily and conveniently used, virtually everywhere, in a simple and efficient manner.

Other purposes and advantages of this invention will appear as the description proceeds.
Summary of the Invention

The invention is directed to a wet wipe for reducing body perspiration, comprising an effective amount of an antiperspirant, impregnated on a sheet material carrier. In the context of this invention, the term "antiperspirant" means any material that, when applied to the skin, reduces skin perspiration. Information concerning antiperspirants can be found in the FDA Tentative Final Monograph, US 47 Federal Register 36492-505 (August 20, 1982). Additional information on antiperspirant agents can be found, e.g., in the International Cosmetic Ingredient Dictionary and Handbook, Seventh Edition, 1997, published by The Cosmetic, Toiletry and Fragrance Association (CTFA).

Throughout this specification, when reference is made to "fabric", or to "sheet material", this term is meant to indicate any type of sheet material that can be impregnated with a liquid solution and which can retain at least some moisture, be it made of paper, fabric or synthetic material, or of any other suitable impregnable material.

The sheet material carrier can be of any suitable type well known in the cosmetic industry. According to a preferred embodiment of the invention, however, the sheet material carrier is a wipe made of non- woven fabric, or a towellette made of paper material. The key features of the sheet material carrier are that it must be impregnable, at least to some extent, it must be sufficiently soft so as not to irritate the skin mechanically, must be moisture resistant at least to the extent that it does not deteriorate on storage, and must be convenient to use in the specific package employed.
Suitable sheet material carriers will be easily identified by the skilled person.

The impregnation solution used will usually contain a preservative conventional in cosmetic uses. Illustrative and non-limitative examples of such preservatives and their average content include iodopropynyl butylcarbamate (0.03%), methylparaben (0.1%) and propylparaben (0.1%)

As will be appreciated by the skilled person, the wipes of the invention not only remove dirt from the skin, but also leave a residual amount of antiperspirant material on the skin, which provides a prolonged antiperspirant effect. Another advantage of the wipes of the invention over, for instance, sticks or rollers, is that they are disposable.

According to a preferred embodiment of the invention the wet wipe further comprises conventional cosmetic additives such as, but not limited to, pH buffering materials, preservatives and perfumes.

The exact content of the antiperspirant and of the water depends on the specific antiperspirant employed, and the skilled person will easily optimize a formulation for his specific requirements. Typically, however, a wet wipe according to the invention comprises about 0.1% to about 30% of antiperspirant, and about 40% to about 75% of water. It is possible, however, to reduce the amount of water, or to replace it entirely, with inert organic materials, such as silicone materials or cosmetically-acceptable glycols to give organic-based or water-organic based solutions or suspensions.
Illustrative and non-hmitative examples of antiperspirants useful in the wet wipes of the invention are:

In another aspect, the invention is directed to a method for manufacturing a wet wipe for reducing body perspiration, comprising impregnating a sheet material carrier with an effective amount of an antiperspirant in, optionally in the presence of conventional cosmetic additives, such as pH buffering materials, preservatives and perfumes.

According to a preferred embodiment of the invention the sheet material

carrier is brought into contact with a solution comprising about 0.1% to

about 30% antiperspirant in about 40% to about 75% of water. Of course,

other non-essential additives can be added, and the addition of such

conventional cosmetic additives is well within the scope of the skilled

person.
